The boy and his father, Adrian Alexander Conejo Arias, drew international attention when they were detained by ICE last week.
The viral image of the boy wearing a blue, bunny-ear hat and a Spider-Man backpack during his father’s detainment has only further fuelled the outrage in Minnesota and nationwide over the immigration crackdown.
Representatives Joaquin Castro and Jasmine Crockett, both Democrats from Texas, visited Liam and his father on Wednesday at a detention facility, the South Texas Family Residential Centre in Dilley. Both reported being alarmed by the child’s condition and are demanding his release.
Mr Castro said the pre-schooler asking for his mom and his family and telling his father he wants to go back to school.
“He seemed lethargic. His father said that Liam has been sleeping a lot, that he’s been asking about his family, his mom and his classmates and saying that he wants to go be back in school with his classmates,” Mr Castro said at a press conference.
He was never alert, the entire time that we were there
Ms Crockett shared her worries for the child in an interview with CNN.
“He was so lethargic. He was never alert, the entire time that we were there. I was very, very concerned about his health,” she said. “His father indicated that he was not eating, that they had determined that he was depressed.”
Ms Crockett also told CNN Liam only has one set of clothes, which his father washes every night after he goes to sleep.
Liam’s mother, Erika Ramos, told Minnesota Public Radio her son’s health was deteriorating.
“The situation of my husband Adrian and my son Liam inside the detention centre is deeply concerning,” she said Monday.
“Liam is getting sick because the food they receive is not of good quality. He has stomach pain, he’s vomiting, he has a fever and he no longer wants to eat.”
The politicians also voiced deep concerns about the state of the Dilley facility as a whole.
Ms Crockett told CNN she heard concerns the drinking water is making some people sick.
Mr Castro said he heard from attorneys who said their clients have been “locked in their room and “there isn’t always proper medical treatment” at the facility.
Department of Homeland Security spokesperson Tricia McLaughlin denied the claims.
